The importance of prototype similarity for physical activity: Cross-sectional and longitudinal associations in a large sample of young adolescents.

ABSTRACT:

Objectives

Physical activity declines during adolescence. The Theory of Planned Behaviour (TPB) is a useful framework for investigating activity but leaves variance unexplained. We explored the utility of a dual-process approach using the TPB and the Prototype Willingness Model (PWM) to investigate correlates of physical activity, and 1-year change in physical activity, among a large sample of adolescents.

Design

A cross-sectional and longitudinal analysis of baseline and follow-up data from the Fit to Study cluster-randomized trial.

Methods

A total of 9,699 secondary school pupils at baseline and 4,632 at follow-up (mean age = 12.5 years) completed measures of past week physical activity and constructs from both behaviour-change models, at time-points 1 year apart. C
